![]() ![]() ![]() The ultra-soft gripper is the latest innovation in the use of soft robotics for underwater sampling, an ongoing collaboration between Gruber and Wyss Founding Core Faculty member Rob Wood, Ph.D. "This gripper is part of an ever-growing soft robotic toolbox that promises to make underwater species collection easier and safer, which would greatly improve the pace and quality of research on animals that have been under-studied for hundreds of years, giving us a more complete picture of the complex ecosystems that make up our oceans." "Marine biologists have been waiting a long time for a tool that replicates the gentleness of human hands in interacting with delicate animals like jellyfish from inaccessible environments," said co-author David Gruber, Ph.D., who is a Professor of Biology and Environmental Science at Baruch College, CUNY and a National Geographic Explorer. ![]() Soft fiber-reinforced actuators grasping (B) Aurelia aurita, (C) Catostylus mosaicus, and (D) Mastigias papua. Inset: Different parts, including the six-actuator palm, can be attached modularly. "This technology can also be extended to improve underwater analysis techniques and allow extensive study of the ecological and genetic features of marine organisms without taking them out of the water."ĭesign of soft robotic gripping device, shown with a four-actuator hub. "Our ultra-gentle gripper is a clear improvement over existing deep-sea sampling devices for jellies and other soft-bodied creatures that are otherwise nearly impossible to collect intact," said first author Nina Sinatra, Ph.D., a former graduate student at the Wyss Institute who is now a mechanical and materials engineer at Google. The gripper is described in a new paper published in Science Robotics. Paulson School of Engineering and Applied Sciences (SEAS), and Baruch College at CUNY offers a novel solution to that problem in the form of an ultra-soft, underwater gripper that uses hydraulic pressure to gently but firmly wrap its fettuccini-like fingers around a single jellyfish, then release it without causing harm. ![]() Now, a new technology developed by researchers at Harvard's Wyss Institute for Biologically Inspired Engineering, John A. ![]()
